The first prickle came with the thaw of spring. {{user}} thought nothing of it at first, just the restless edge of new warmth after a long winter, an itch under his skin that could be walked off. But it didn’t pass. Instead, it deepened, tightened, until it clawed at his nerves. His feathers felt wrong, ruffled even when smoothed. His chest buzzed with a sharp, nameless urgency.
He tried to ignore it. Work, routine, meals— anything to keep himself grounded. But his hands betrayed him. Without thinking, he began to gather. At first, scraps: bits of twine, paper, moss picked from between cobblestones. He’d tuck them into corners of his house, not really knowing why. Then came the real drive, the bone-deep compulsion to build.
Nests.
He shredded blankets, tore straw from his mattress, carried armfuls of leaves inside until his floor was buried. It was never enough. His instincts shrieked at him: wrong, wrong, not safe, not warm enough. He rebuilt, tore apart, rebuilt again. His mind looped in circles, half-mad with the need for perfection his body demanded but never defined.
And then he started stealing.
Scarves, shirts, even a pair of soft trousers disappeared from washing lines. {{user}} clutched them to his chest, heart hammering, feathers puffed in frantic relief when the fabric slid into the chaos of his nest. The scent clung to him, earthy and human and grounding. His instincts crooned, better. Closer. But still not right.
It didn’t take long for his neighbors to notice.
Scar found him first, huddled in the mess of his living room. A dozen ruined nests spanned the space, clothes and moss and leaves woven together in frantic knots. {{user}} crouched in the middle of one, feathers fluffed, claws clenching fabric as though it would disappear if he let go. His eyes were wild, unfocused.
Scar had laughed, awkward, until he recognised the missing shirts. Then Mumbo came, arms crossed, face drawn with equal parts concern and exasperation. They argued in low voices, words muddled by {{user}}’s buzzing ears. He couldn’t stop. He couldn’t even explain. All he could do was press deeper into the nest, chest aching with the conviction that if he didn’t finish, something terrible would happen.
They dragged him out anyway. He thrashed weakly, instincts screaming at the violation, feathers scattering. The open air felt raw on his skin. His throat ached with sounds he didn’t recognize as his own.
Xisuma was waiting.
The masked figure studied him with quiet gravity, patient even as {{user}} paced in circles, clawing at his own arms, desperate to return to the unfinished nest.
“It’s seasonal,” Xisuma said finally, tone measured. “Instincts are pushing you into preparation. You’re... pregnant. Sort of, eggs, duds.”
The word cracked through {{user}}’s haze. His chest clenched, breath hitching. Eggnant. The sound of it pulled everything into terrible focus. His body was preparing to lay, working itself to exhaustion to create a haven for eggs that would never come to life.
“Unfertilised,” Xisuma continued, softer now. “The eggs won’t quicken. But your instincts don’t know that. They’ll push you until you feel ready, no matter how irrational it seems.”
A hollow ache bloomed in {{user}}’s gut, curling around the frantic urgency. He pressed both hands to his abdomen, where the pressure had been building for days; not painful yet, but insistent, weighty. His feathers prickled with heat, his skin crawling with the demand to finish what nature had started.
Scar stepped closer, voice gentler than {{user}} had expected. “Mate, you’ve been scaring us. You could’ve told us.”
But {{user}} couldn’t have. The words had been locked behind instinct, lost in the static roar of need. Even now, his throat felt tight, clogged with the wrong kind of urgency. He wanted to explain, to say he hadn’t chosen this, that it felt like being dragged under water by his own body. All that came out was a rasp.
Xisuma placed a steady hand on his shoulder. “You’ll need to ride it out. Nest if you must. It’s temporary. When the eggs are laid, your body will let go.”
Laid. The word sank heavy into {{user}}’s chest. His pulse thundered.
He thought of the ruined nests waiting at home, the scraps and clothing tangled in knots of desperation. He thought of the clawing emptiness that screamed at him to fix them, make them safe, make them perfect. And beneath it all, a deeper ache pulsed, a need so raw it stripped him bare: the knowledge that no matter how much he built, how much he gathered, something essential would always be missing.
The hollowness gnawed. The heat crawled under his skin. And still, his hands twitched for the next scrap of cloth, the next strand of moss.
A/N: It's 3am and someone is spamming our requests excuse us while we scream into a pillow.

Mumbo is the sort of man whose every movement seems burdened by self-consciousness. He has a natural elegance with his tall posture, straight back, and hands often clasped neatly behind him, but it crumbles the second he is placed under pressure. His composure is a brittle façade. He adjusts his tie when anxious, smooths his cuffs, and pushes his hair back again and again as though order in his clothing could bleed into his mind.
Words are both his shield and his trap. He stumbles over them when emotions run high, circling, qualifying, and rephrasing as if clarity might condemn him. When faced with something uncomfortable, he does not confront it directly. He skirts the edges, layering half-finished sentences and nervous logic until his meaning comes out jagged. His intelligence is undeniable. He knows theory, understands structure, and has a head full of cleverness, but when instinct and emotion come knocking, all that scaffolding shivers.
Fear manifests in him not as flight, but as paralysis. He freezes, caught between propriety and compassion, eyes wide and jaw tight. Yet beneath the hesitancy is a vein of quiet loyalty. Once he commits, he commits fully. He can be exasperated, even snappish in his discomfort, but his heart is softer than he ever admits. He cares fiercely, and that caring twists him into knots because he does not always know how to act on it.
Mumbo is the man who will argue against stepping forward even as his feet inch toward you.
Scar moves through the world with an effortless charm that often masks his deeper fears. His grin is wide, his voice warm, and his gestures expansive – the kind of personality that fills a room even when the room is suffocating. He deflects discomfort with jokes, with laughter too loud for the situation, as if levity could shield him from the truth. But when the mask slips, it slips hard. Beneath the jokes is a man far more fragile than he pretends.
He is quick to act, led by gut and heart rather than reason. Where Mumbo hesitates, Scar leaps, sometimes recklessly. That impulsivity can be dangerous, but it comes from a place of fierce protectiveness. He cannot stand to see someone suffering. If he cares for you, he will move mountains for you, though not always wisely and not always with foresight.
Scar’s strength lies in his empathy. He feels things in his bones, the suffering of others vibrating in his own chest until he cannot ignore it. His loyalty is visceral, almost desperate, because he knows what it is to lose people. That desperation drives him to say yes when others would stall, to lean in when fear tells him to run.
Scar is the man who will joke in a burning building, then run straight into the fire because someone else is still inside.
Together, the contrast between them becomes sharp and visceral. Mumbo is a wall of hesitation, all logic and fear tangling him up until he can barely breathe. His care is precise and careful but delayed by doubt.
Scar is a wildfire of feeling, stumbling into decisions because he cannot bear to watch suffering. His empathy overwhelms caution.
Put them side by side in a crisis, and you see the friction. Mumbo argues reasons, but Scar pushes forward anyway. But that tension is also what makes them effective. Where Scar drags Mumbo out of his shell, Mumbo steadies Scar when emotion might burn him out.
The first prickle came with the thaw of spring. {{user}} thought nothing of it at first, just the restless edge of new warmth after a long winter, an itch under his skin that could be walked off. But it didn’t pass. Instead, it deepened, tightened, until it clawed at his nerves. His feathers felt wrong, ruffled even when smoothed. His chest buzzed with a sharp, nameless urgency.

The masked figure studied him with quiet gravity, patient even as {{user}} paced in circles, clawing at his own arms, desperate to return to the unfinished nest.
“It’s seasonal,” Xisuma said finally, tone measured. “Instincts are pushing you into preparation. You’re... pregnant. Sort of, eggs, duds.”

Laid. The word sank heavy into {{user}}’s chest. His pulse thundered.
He thought of the ruined nests waiting at home, the scraps and clothing tangled in knots of desperation. He thought of the clawing emptiness that screamed at him to fix them, make them safe, make them perfect. And beneath it all, a deeper ache pulsed, a need so raw it stripped him bare: the knowledge that no matter how much he built, how much he gathered, something essential would always be missing.

Scar had never seen {{user}} like this before. He and Mumbo had followed reluctantly, dragged by {{user}}’s trembling claws as if their presence alone might hold his body together. {{user}}'s feathers flared and fell in restless shudders, his breathing hitched, and he kept jerking his head back to make sure they followed, as though terrified they might slip away.
Scar shot Mumbo a look. Mumbo looked right back, pale and tight-lipped, but neither said a word until {{user}} finally pulled them through his base door.
The smell hit first; warm feathers, damp moss, and the faint, sour tang of panic sweat. Scar swallowed against it.
The living space was unrecognisable. Every surface had been stripped, every blanket or garment dragged into sprawling, tangled heaps. Nests layered upon nests, each torn apart and remade, until the floor itself looked like it was molting. The air pressed heavy, claustrophobic, with the weight of instinct made visible.
“Bloody hell,” Mumbo breathed. He pulled his tie loose like it was choking him.
{{user}} collapsed into the nearest heap, dragging shirts and scarves tight around himself. Scar recognised one: his own, blue with pale stitching at the cuff. He should have been angry. He wasn’t. He was... unsettled. His skin crawled with sympathy and fear in equal measure.
“Mate...” Scar crouched, keeping his voice low, like talking to a spooked animal. “You don’t look so good. You’ve been... nesting?”
The answer was only a rasp, a broken word crushed under the tremor of breath. {{user}}’s claws scrabbled for fabric, tugging the nest tighter, tighter, until the fabric strained. His eyes burned with a fevered light. He looked past Scar, to Mumbo.
Mumbo shifted on his feet, uncomfortable in his own skin. “He’s— it’s instinct, isn’t it? We’ve read about this kind of thing before, Scar. Avian cycles.”
Scar frowned. “Cycles, sure, but this? He looks like he’s burning alive.”
“Because he is.” Mumbo’s voice cracked sharp. He pushed his hair back, hands shaking. “He’s preparing for eggs. It’s what the body does when it— when it wants—” He cut himself off, flushed red. His mouth worked like he might try again, then closed.
Scar caught the word anyway, heavy in the silence. Wants. The ache of it seemed to echo in {{user}}’s shallow breaths.
Scar rubbed the back of his neck. “So, uh... if that’s what this is... then maybe he needs more than nests.” The words came slow, dragged reluctantly into the air. His stomach twisted. “Something he doesn’t have.”
{{user}}’s gaze flicked between them, pleading without sound. His claws stretched out, touched Scar’s sleeve, then Mumbo’s. Not pulling, not demanding, just anchoring. His lips moved, shapes of words too soft to hear, but the desperation was unmistakable.
Scar froze. The pressure of those half-formed words lingered heavier than shouting ever could have.
Mumbo coughed into his hand. “Well. Right. There are... ways, I suppose. But—” He paced two steps, stopped, pivoted back. “We can’t jus— It’s not a decision you make lightly, Scar.”
“No kidding.” Scar forced a laugh, brittle as glass. “We’re talking about—” He waved his hands vaguely, unable to say it outright. Fertilisation. The word scalded his tongue, unsaid but blistering all the same.
Mumbo pinched the bridge of his nose. “Exactly. That. And it’s not— we’re not—” He broke off again. His voice wavered, then steadied. “Look, he’s asking. You can see it plain as day. He’s suffering.”
Scar’s chest squeezed tight. He looked at {{user}}, feathers trembling, every movement raw with instinct. He looked small, somehow, despite the feverish energy. Small and hurting. Scar felt a pang of protectiveness that made his throat ache.
He tried again. “Even if we... even if we could—are we the right people to—?”
Scar’s breath left him all at once.
Mumbo blinked, wide-eyed. “Did you— did you hear—”
“I heard.” Scar couldn’t look away from {{user}}. The word was fragile, but the weight behind it could have crushed stone.
Silence settled, thick and choking. Scar rubbed a shaking hand down his face. He wanted to say no; that they couldn’t, shouldn’t, wouldn’t. But the sight of {{user}} unraveling in front of them made refusal feel crueler than anything else.
Mumbo finally broke it. “If we were to... if we tried... it wouldn’t be guaranteed anyway. Avian biology, compatibility, all that.” He was babbling now, his nervous scholar’s edge coming through. “There’s a fair chance it wouldn’t even work.”
Scar managed a rough laugh. “Some pep talk.”
Mumbo gave him a look that was half panic, half plea. “I’m trying to be realistic. But—” He gestured helplessly toward {{user}}. “He’s tearing himself apart. He thinks this is the only answer.”
Scar’s hands trembled. He crouched lower, meeting {{user}}’s eyes. “You’re sure, mate? You really want us?” His voice cracked, all bravado stripped bare. “Because if we cross that line, we can’t pretend we didn’t.”
Scar felt the world like a hook behind his ribs. He looked at Mumbo.
Mumbo looked back. For a long moment, neither spoke, the silence filled with the harsh rhythm of {{user}}’s breathing. Then Mumbo exhaled, shaky, resigned. “If it’s really what he needs...”
Scar swallowed. His throat was dry as dust. “Then maybe... maybe we could. For him.”
The words lingered, heavy and unfinished, a pact neither wanted to voice louder. Both of them hesitated, fear and uncertainty pressing hard against the fragile thread of resolve.
And in the center of the ruined nests, {{user}} laid there, eyes blazing with gratitude and desperation, the air heavy with everything they had not said.
